摘要： PURPOSE:To easily change an on-off form while conducting common use of the first/second fixed terminals arranged in both sides of a common terminal. CONSTITUTION:In a switch, a switch handle 4 is reversely swiveled to switch a contact by reversely swiveling a movable contactor 6, by arranging the first fixed terminal 2 in one side of a common terminal 1 and also the second fixed terminal 3 in the other side, to provide constitution such that a direction relating to the common terminal 1 can be reversed, in at least one of the first/second fixed terminals 2, 3. An eccentric terminal part 5, placed in a contact condition or noncontact condition relating to the movable contactor 6, is provided in the first fixed terminal 2 or the second fixed terminal 3 of reversing a direction.

摘要： PURPOSE:To magnetize magnetic material with intensity wherein the magnetic material is magnetically saturated, without working on yokes, and clarify the boundary between the magnetized region and the non-magnetized region, by arranging leakage magnetic flux cutting-off members composed of electrically conductive material between the magnetizing yokes. CONSTITUTION:A coil 2 is wound around each yoke 1a-1d in the manner that magnetic pole surfaces 3 of adjacent jokes 1a-1d in the peripheral direction turn to different magnetic polarity. Between the adjacent yokes 1a-1d, leakage magnetic flux shielding members 4 composed of electrically conductive material like copper is arranged. By arranging such magnetic flux shielding members 4, a current is induced in the leakage magnetic flux shielding member 4, accompanied by the change of leakage magnetic flux, and consumed as the loss of heat energy, so that the adverse influence of the leakage magnetic flux upon the magnetic material can be reduced. In the case where the leakage magnetic flux shielding members 4 are arranged so as to come into close contact with adjacent yokes 1a-1d, the magnetization distribution in the non-magnetized region becomes wavy state, and the rise of the magnetized region becomes sharp.
